How are some organs in female reproductive system work together to hold baby during pregnancy?

During pregnancy, the uterus serves as the primary organ that houses the developing baby, expanding to accommodate its growth. The cervix acts as a protective barrier, maintaining the pregnancy by keeping the fetus secure within the uterus. Additionally, the amniotic sac surrounds the fetus, providing cushioning and a stable environment, while the placenta facilitates nutrient and oxygen exchange between the mother and the baby. Together, these organs create a supportive environment essential for fetal development.
